Mitsubishi R61P MELSEC iQ‑R Series Power Supply Module 100‑240V AC 5V 6.5A

Mitsubishi Electric R61P is a compact AC input power supply unit for the MELSEC iQ‑R series PLC system. Converts 100‑240 V AC input to 5 V DC output (6.5 A), supplying stable power to the backplane and all connected modules in the main base or extension base unit. Includes an error contact (ERR) output for failure monitoring. Backplane mounted via the base unit.
